Deer Whistle Keeps Animals Off The Road
Horses, deer and other wildlife flee from approaching cars or trucks fitted with a new ultrasonic "beeper" that fits to the front bumper or grill and emits a high-pitched sound that some animals hear up to 1/4 mile away.
Developed in Austria and tested extensively throughout Europe, the new warning device is already catching on in the U.S. with companies that operate large truck fleets, and among law enforcement agencies. A law has even been introduced in Delaware that would require it to be fitted to all state vehicles.
The Sav-A-Life, as it's called, is a 2-in. long bullet-shaped device that sticks to the car with an adhesive backing. At about 30 mph, air rushing over and through it creates an ultrasonic sound heard by some animals up to 1/4 miles away. At the high pitch of 16,000 to 20,000 Hertz, however, humans can't hear it and inside the car it can't be heard by either humans or animals.
The only animals among those tested so far that don't respond are cattle, sheep and camels. The Sav-A-Life sells for $24.95 plus $2 post-age and handling.
